We can supply quality Neodymium Magnet. The NdFeB segments are use to Sensor,Motor,Loudspeaker etc.

1.You are buying ONE lot of 20 Magnets. Dimensions in MILLIMETERS of the completed MOTOR ring: 54 outer diameter x 46 inner diameter x 20 long(54 mm x 46 mm x 20 mm)

2.Nickel (Ni) Plated (silver-like shine)

3.Grade: N48 - Extremely powerful magnetic material

4.These arc segments are magnetized through their thickness in order to be able to create a ring (see diagram below). ASSEMBLY REQUIRED:  It takes 18 arc segments - 9 with N Poles on the outer diameter and 9 with S Poles on the outer diameter - to complete a ring.  

5.PLEASE NOTE: As with ALL neodymium magnets, these arc segments are very fragile. Therefore, 2 extra arc segments will be included with each lot purchased. One of each polarity. Please be careful when assembling.
